Inverter doesn't run motor
Posted: Mon Feb 19, 2024 1:14 pm
Hi Everyone, I have a small problem with my Rev2 Inverter. 5 years ago, after building the kit, it would run the (Enova) motor ok on basic tests. The motor has been fitted in the car for a while now, but I cannot get it to run. Nothing obvious (to me) has changed. Has anyone got any Ideas??
The motor turns freely by hand ( or at least by screwdriver through a hole). I'm using 39v from batteries via a 15A fuse, to test.
Checking waveforms, I get more of a triangle form at the gate driver input (see pic) and (to me) a peculiar form on each of the phases to the motor.
All my readings/waves are the same for all of the 3 inputs/outputs. What am I doing wrong? Thanks in advance for Any ideas.
